What you need this for? It is not used anywhere in this patch and by
mips/kvm code in general.
I did some digging around myself, since the linker keeps complaining that it can't find min_low_pfn when compiling the KVM module. It seems that it is indirectly pulled in by the cache management functions.
If it is really needed, then the export should probably be done at the
site of the min_low_pfn definition, not in some random architecture file.
An alternative is to fix the cache management functions so they don't
require the export.
